The soret effect
WebThe Soret effect is the resulting phenomenon in which an temperature gradient induces a concentration gradient in multicomponent mixtures. The Soret coefficient is the ratio of … WebThe Soret coefficient is not a constant; it may vary due to changes in concentration or temperature. A positive Soret coefficient means a thermophobic particle. The Soret coefficient can change sign as a function of concentration [ 1] or temperature [ 3] (see Fig. 2 ).
